1. THE DESERTS -DEFINITION. -FEATURES. -BIOTIC AND ABIOTIC FACTORS THAT INFLUENCE DESERT BIOME. -MOST REPRESENTATIVE DESIERTS IN OUR PERU. DELGADO ENVIRONMENT ELERA, REYNER San José de Moro, September 2014
2. DESERT A desert is an area of the earth's surface totally or almost totally uninhabited. A desert can be a sandy or stony terrain that lacks vegetation due to low rainfall. The harsh environmental conditions mean that these deserts have little stable population DELGADO ELERA, REYNER. CHARACTERISTICS OF THE DESERTS. Temperatures are generally high, but nights can be cold. Its climate is extreme with temperatures of 50 ° C during the day and –20 ° C at night. It is the ecosystem that presents water scarcity. The ground is covered with sand as a result of the disintegration of rocks. The relief presents plains, dunes and in some places oases. There are counter winds and rains are very scarce. Deserts form the largest area of the earth's surface. BIOTIC AND ABIOTIC FACTORS THAT INFLUENCE DESERT BIOMA BIOTIC FACTORS THAT INFLUENCE DESERT BIOME These are the living beings of an ecosystem that survive. They can refer to the flora, fauna, humans of a place and their interactions. Individuals must have specific behavior and physiological characteristics that allow their survival and reproduction in a defined environment. The condition of sharing an environment engenders a competition between species, given by food, space, etc. Depending on the region: In the desert only some animals manage to survive: camels, lizards, spiders, owls, rats, kangaroo, mice, a variety of snakes, hawks, scorpions, birds, squirrels among others. In the same way, in the fauna, only some plants manage to survive. These protect themselves from other animals with the thorns they have and with their thick layer of skin, some of them are: cactus, palm trees, nopales, bushes, grasslands, weeds in oases, etc.
3. Plants and animals that live in the desert are conditioned to withstand extreme temperatures with minimal water. ABIOTIC FACTORS THAT INFLUENCE DESERT BIOME Abiotic means lifeless. They are the different components that determine the physical space in which living beings inhabit; among the most important we can find water, temperature, light, soil, humidity, air and nutrients. They are the lifeless factors. Deserts are known for their extreme abiotic factors. Varied temperature and scarce fluvial precipitation. Sunlight, climatic factors such as: humidity (very low) and temperature (high during the day, very low at night); rocks, sand or very dry soil, atmospheric gases, very strong barometric pressure. Rocky terrain, wind processes are important factors in the formation of the landscape. They have an average rainfall of 200 to 500 mm per year. MOST REPRESENTATIVE DESERTS OF PERU 1. DESERT OF SECHURA One of the most representative deserts of Peru is that of Sechura, located in the northwest of Peru, just between the Lambayeque and Piura regions having a length of 150 kilometers by a width of 100. It is located 55 km southwest of the city of Piura. It is the widest area of the coastal desert in Peru, it has an area of more than 5000 square km. This desert is an arid plateau formed by materials from the Tertiary, with little vegetation, which includes several intermittent lagoons. The aridity of the climate and the unproductive soils limit the settlement of the population, except in the oases that constitute the mouths of the Piura rivers, to the north, and Lambayeque, to the south; agriculture is possible in these areas.

Give the two ways nitrogen can be fixated so plants can use it to grow.
[tex]\huge\mathfrak\red {Answer:}[/tex]
FixationNitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
Biologically:Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
Through lightning:Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

Which statement regarding the structure or function of ribosomes is correct?
a. In eukaryotes, the ribosomes found in chloroplasts and mitochondria are 70S ribosomes, which are similar in size to prokaryotic ribosomes.
b. Ribosomes are found both free-floating and attached to the rough endoplasmic reticulum in eukaryotes and in prokaryotes.
c. Ribosomes are the sites of lipid biosynthesis in both prokaryotes and eukaryotes.
d. The ribosomes in the prokaryote are slightly larger than those found in the eukaryotic endoplasmic reticulum.
Answer:
C
Explanation:
Ribosomes are in Eukaryotic and Prokaryotic cells
I think this is correct
Ribosomes are the site for the protein synthesis. In eukaryotes, the ribosomes found in chloroplasts and mitochondria are 70 S ribosomes, which are similar in size to prokaryotic ribosomes. The correct answer is option a.
What is RER and SER ?It is the rough endoplasmic reticulum and the smooth endoplasmic reticulum.
Eukaryotes and the prokaryotes both got the DNA and the ribosomes as well. The ribosomes which are present in eukaryotes are 80 S and the prokaryotes have 70 S type of ribosome units thus the Mitochondria along with the chloroplast in the prokaryotes have their own ribsomes as well as DNA which is 70 S that is same to the prokaryotes.
Endoplasmic reticulum is the site of lipid synthesis and with that they do show the association with ribosomes for the protein synthesis but not in prokaryotes but that happens in the eukaryotes.

is ther a tutor available can you plese check
Answer:
The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. ... When that reacts with oxygen (O2) in the cells, it produces carbon dioxide (CO2) and water (H2O). C6H12O6 plus 6O2 gives 6CO2 plus 6H2O plus energy.

The structure of jupiter and sun mostly made up of hydrogen and helium.
What are the characteristics of hydrogen and helium?Hydrogen and helium are the lightest elements in the periodic table. They exist as gases at room temperature and are the two most common elements in the universe, with hydrogen making up about 75% of all matter.
It will form a mixture of two of the lightest gases known. Though Hydrogen atoms (H) turn into hydrogen molecules (H2) to form a very reactive, flammable, and explosive hydrogen gas, Helium (He) atoms form an inert gas.
The key difference between hydrogen and helium is that hydrogen is a diatomic gas, while helium is a monatomic gas. Helium has a fully filled s orbital (1s2), but in hydrogen, there is only one electron, so it is unstable.
